Microchip Technology's AT45DB021B-RU is a 2-Megabit DataFlash memory IC, organized as 256K x 8 bits. This NOR Flash device operates synchronously via an SPI serial interface, supporting clock frequencies up to 20 MHz. The memory is structured into 1024 pages, each with 264 bytes, facilitating efficient data management. Key features include hardware write protection and robust endurance of 100,000 program/erase cycles. The AT45DB021B-RU operates over a temperature range of -40°C to +85°C and requires a supply voltage between 2.7V and 3.6V. Packaged in a 28-lead SOIC (PDSO28) with a 1.27mm terminal pitch, this component is suitable for applications in industrial control, consumer electronics, and communication systems demanding reliable non-volatile data storage.
